Rooney Mara is fast becoming the spokesperson for the little black dress. Fact. She’s worked a multitude of trends, ranging from monochrome to lace to cut-out, so we weren't surprised when Ms. Mara graced the Paris premiere of The Girl with the Dragon Tattoo in yet another timeless trend: the embellished dress. Well, we know one thing for sure...this girl knows how to rock a LBD. The sleeveless Louis Vuitton mini-dress sported detailed bead embellishment in a faux sweetheart neckline and the actress kept the look fierce with a simple leather belt. The strappy Givenchy sandals gave a minimalistic edge to the outfit and kept the focus on the gorgeous dress. Of course Ms. Mara topped it all off with her trademark straight ’n’ sleek hair and a crimson pout. Now if you want to make like Ms. Mara and brave the cold in a cute mini-dress, cast your eye over Team LBD’s pick of key pieces to get the year started in style- but maybe invest in some tights!
